Wis. Admin. Code Department of Natural Resources § NR 514.05 - Engineering plans

The plan of operation for all new landfills and expansions of existing landfills shall contain a set of engineering plans which are drawn in accordance with ss. NR 500.05 and 504.07 to 504.12, and the following requirements. Engineering plans shall be drawn on standard 24 inch by 36 inch plan sheets. If facility details cannot be shown on standard plan sheets at a 1:100 scale, the engineering plans may be drawn on 30 inch by 42 inch plan sheets. All plan sheets except the title sheet, existing conditions sheet, cross-sections and details sheets shall utilize the existing conditions sheet as a base map. For complex plans, existing conditions within the landfill area may be shown by lighter lines or may be eliminated.

(1) TITLE SHEET. A title sheet shall be included indicating the project title, who prepared the plans, the date the plans were prepared, the applicant for whom the plans were prepared, a table of contents, a map showing the location of the facility within the county or multicounty area, the location of the county or multicounty area within the state and the area to be served.
(2) EXISTING CONDITIONS. An existing conditions plan shall be included consisting of a detailed topographic map of the proposed facility landfill and all areas within 1,500 feet of the proposed limits of filling prior to development. The minimum scale shall be 1" = 200 feet with a maximum 2 foot contour interval. The contour interval selected shall be sufficiently small to clearly show surface water flow patterns within and around the landfill. All elevations shall be related to USGS datum. The plan shall identify and define the following:
(a) Surface waters including intermittent and ephemeral streams and wetlands.
(b) Property boundaries, the proposed landfill boundary, and the proposed limits of filling.
(c) A north arrow, landfill survey grid, a formula for converting grid locations to the state plane coordinate system, and the locations of all existing and proposed survey monuments.
(d) Residential and commercial structures and other buildings.
(e) Locations of all soil borings, all existing and abandoned groundwater monitoring wells, and all public and private water supply wells, and the general locations of all known septic system drain fields within 1,000 feet of the landfill area or within 500 feet of any monitoring well.
(f) The locations of all other landfills, demolition landfills and all other solid waste facilities for the processing, storage or composting of solid wastes.
(g) Utility lines, underground pipelines and electrical lines, access control and other constructed topographic and drainage features.
(3) SUB-BASE GRADES AND BASE GRADES. Plan sheets shall be included which depict the sub-base grades, all sub-base appurtenances such as lysimeters or drain pipes, and the base grades.
(4) ENGINEERING DESIGN FEATURES. Separate plan sheets shall be included to depict the overall landfill area and the limits of liner construction and filling. The plan sheets shall depict the layout and slope of the liner system and leachate collection system including pipes, sumps, riser pipes on interior sideslopes, manholes, trenches, berms, lift stations, permanent storm water control structures, pipe cleanouts and other pertinent structures. Invert elevations shall be provided at any changes in grade for all leachate and groundwater collection and transfer systems.
(5) PHASING. A series of phasing plan sheets shall be included to show landfill development through time. The location of peripheral features such as support buildings, access roads, drainage ditches, sedimentation basins, any other storm water management features and screening berms shall be indicated on this plan. At a minimum, a separate plan sheet shall be provided for initial construction and for each subsequent phase of development or new area where substantial construction is to be performed. These subsequent phasing plan sheets shall present the final filling surfaces in the previous phases of development; the limits of clearing, grubbing and topsoil removal; the base grades of the new phase of filling; the anticipated surface contours of soil stockpiles at the time depicted on the plan sheet; and storm water management features. Each plan shall include a list of construction items and quantities necessary to prepare the phase of development indicated on the plan.
(6) STORM WATER MANAGEMENT. Plan sheets shall be included which depict the features to be constructed for storm water management at the time of initial construction, during phased development, and after closure of the landfill. Plan sheets shall include the locations of sediment basins, drainage ditches, auxiliary sediment traps, and the anticipated extent of cleared ground and stockpiles during each major phase of landfill development. Plan sheets shall include a list of anticipated actions and materials needed for sediment and erosion control.
(7) WASTE FINAL GRADES AND FINAL TOPOGRAPHY. A final waste grades plan sheet shall be included to indicate waste final grades, including daily and intermediate cover. A final topography plan sheet shall be included to indicate the appearance of the entire facility following closure including storm water drainage features and the location of gas extraction wells and all other penetrations of the final cover.
(8) MONITORING. A facility monitoring plan shall be included to show the location of the design management zone as determined under s. NR 140.22 and all devices for the monitoring of leachate quality and quantity, unsaturated zone water quality and flow rate, groundwater quality, storm water quality, gas production, gas migration, gas condensate and surface settlement.
(9) LONG-TERM CARE. A long-term care plan sheet shall be included showing the topography of the landfill following closure. This plan sheet shall list those items anticipated to be performed during the period of long-term care including the proposed schedule for monitoring and maintenance of the landfill. This information may be included on the final topography plan sheet if clarity is not compromised or reference may be made to the appropriate section of the operations manual and design report.
(a) A minimum of 2 cross-sections in each direction shall be drawn perpendicular and parallel to the facility baseline through the major dimensions of the landfill. The location of the cross-sections shall be illustrated by a reduced scale plan view on each cross-section. Each combined engineering and geologic cross-section shall show:
1. Existing grades.
2. Sub-base, base, top of leachate collection blanket grades and final grades.
3. Soil borings and monitoring wells which the section passes through or is adjacent to.
4. Soil and bedrock types. For clarity, a number or symbol shall be used to label major soil units instead of extensive shading.
5. Stabilized water table contours.
6. Leachate collection and monitoring systems.
7. Gas venting or extraction and monitoring systems.
8. Limits of refuse filling.
9. Erosion, storm water and sediment control structures.
10. Access roads and ramps on the perimeter of the disposal area and within the active fill area.
11. The filling sequence or phasing interfaces and other facility features.
(b) Cross-sections shall be included to illustrate all important construction features of the liner, final cover, lysimeters, leachate collection trenches and sumps, liner penetrations, sideslope risers, piping systems for gas and gas condensate and drainage systems for storm water.
(c) Detailed plan view sheets shall be included for piping outside the limits of filling for leachate header and drain lines, gas and condensate lines, and leachate forcemains, with notations of pipe slope and intersection elevations with appurtenances such as manholes, lift stations, collection tanks and gas blower stations.
(11) DETAILS. Drawings showing details and typical sections shall be included for storm water control structures; access roads; fencing; final cover and base liner systems; leachate and gas control systems such as pipe bedding, manholes, transfer lines, force mains and storage tanks; leachate transfer lines which extend through the liner; groundwater and unsaturated zone monitoring devices; and buildings. This plan sheet shall include all other construction details such as leachate and refuse containment berms between subsequent phases of development.
